cooktspindledwhich 'is-#rotatable and rhas its; M outwardly .extendingshaftl18 connected sto;v fthe 105` arm 12, as heretofore described. The"spindlehz` is retained in position by the gland yplug screw threaded. through the.; side' walk of casing 1 and` into the basefl andurnishinga bearin'gforthe shaft 13. It will be noted also that the spindle 16 and its plug 34 serve to retain the base 19 in position relative to the casing 1. Upon the outer cylindrical surface of the spindle 26 there is formed diverging grooves 27, as shown in Fig. 3, which at their upper ends communicate with' an aperture 28 at the bottom of the soldering chamber 1G and at their lower ends communicate through slots 27a and 27h in the base member 19 with the ducts 2e and the similar ducts upon the face of the jaw 21. The angular extent of the grooves 27 upon the surface of the spindle 26 is such that a very slight rotative movement of said spindle is suiiieient to open or close the valve.

The provision of the solder distributing ducts 2d on the outside of the soldering iron 22 is found to give a steady and uniform feed for the solder upon the outside or working point of the iron 25 as well as to readily cover said working point 25 with solder and prevent the chance of oxidation thereof. Such soldering irons are usually made of copper and when heated tend to quickly form a scale when exposed to the atmosphere. It is therefore of great importance to keep the exposed working end of the tool covered with solder as far as possible. Also the arrangement of the dis- Y tributing ducts 24 which terminate, as shown,

" above the working end 25 of the soldering iron tends to prevent the solder from forming into drops as it emerges from said ducts upon the surface of said member. In this way, the solder conducted to the working end of the tool tends to spread out over said surface and completely cover it, and provides both a proper working action for the point 25 as well as a protection against the formation of scale.

In using the present soldering tool, the solder to be melted is placed in the chamber 14 and the electric heat turned on to fuse it. An indication of the amount of heating necessary for the tool is afforded by the point at which the fused solder begins to run or feed to the working end 25.

" When this occurs, the ciurent may be shut off and the tool worked with as long as solder' will run, which will be a considerable length of time due to the maintenance of heat by the molten solder in the chamber 14, 16. As soon as the "solder fails to run down to the working point of the member 25, the current may be again turned on to reheat the solder. In this way, a considerable saving of electrical current may be obtained by use of the present tool and the danger of over-heating the tool avoided.

It will be appreciated from the foregoing description that the several principal parts making up the complete tool are separable and removable for replacement and repair. The assembly of these parts into the tool may be accomplished as follows. The porcelain sleeve 17 with its heating wire 18 is first slid onto the tubular portion 16 and the base member 19 is screwed onto the bottom of the tubular portion. These parts are then inserted into the casing 1 from the top with theprojection 31 in the slot 32; and the socket for the spindle 26 is registered with the plug opening at the bottom of casing l. The slide 33 l may then be fitted in place in the slot 32, the

spindle 26 inserted and the plug 34 screwed home.

Finally the work member 22 is fitted in placeV and held by screw 23, and the wires of cable 4 connected to the terminals 29, 29. When iilled '4 :with solder and the cover 6 is locked on, the tool ing chamber, electric heating means associated with said chamber to melt the solder therein, chuck jaws at the lower end of said casing, a soldering member secured in said jaws, the inner faces of said jaws being formed with grooves to provide solder distributing ducts leading down the outside of said soldering member, and a valve for controlling communication between the solder chamber and said solder distributing ducts.

In an electrically heated soldering tool, in combination, a casing providing a solder receiving chamber, electric heating means associated with said chamber to melt the solder therein, chuck jaws at the lower end of said casing, a soldering member secured in said jaws, the inner faces of said jaws being formed with grooves to provide solder distributing ducts leading down the outside of said soldering member, a valve for controlling communication between the solder receiving chamber and said solder distributing ducts, a handle supporting said casing, a valve operating member adjacent said handle, and a control switch for the electric heating means mounted on said handle.

5. In an electrically heated soldering tool, in combination, a casing, a solder receiving chamber with a depending portion of reduced diameter removably tted in said casing, an insulating sleeve removably iitted on the reduced lower portion of said chamber and carrying an electric current heating wire, a base member detachably secured to said chamber depending portion, and fitting within the lower end of said casing to close the same, and a soldering member detachably fastened to said base member.

5. In an electrically heated soldering tool in combination, a hollow casing forming within the same a solder receiving chamber, electrical heatber held within said holding member with the.

lower end of said soldering member exposed, one or more distributing ducts having communication jacent side or sides of said holding member and said soldering member, said duct or ducts terminating on the exposed side of said soldering member at a distance above its lower end whereby with 'said chamber and formed between the adthe molten solder may be conducted from said chamber to said exposed side of said soldering member and run down the outside of the same to the point thereof.
